Novel heteroleptic iridium complexes are disclosed. The complexes contain a phenyl pyridine ligand and another ligand containing a dibenzofuran, dibenzothiophene, dibenzoselenophene, or carbazole linked to an imidazole or benzimidazole fragment. These complexes are useful materials when incorporated into OLED devices.

A simple and general copper‐catalyzed method has been developed for transformations of various functionalgroups (I, N3, SO2R, OH, NH2, and NO2) on aromatic rings fromarylboronicacids in water under air. The protocol uses cheap and readily available inorganic salts (KI, NaN3, NaSO2R, NaOH, NaNO2) and aqueous ammonia as the functional‐group sources, simple Cu2O/NH3 as the catalyst system, environmentally
简单和一般铜催化方法已被开发用于各种官能团的变换( I, Ñ 3, SO 2 R, OH, NH 2,和 NO 2)从在水中的芳基硼酸的芳环在空气中。该协议使用廉价且容易获得的无机盐(KI,NaN 3,NaSO 2 R,NaOH,NaNO 2)和氨水作为官能团来源,即简单的Cu 2 O / NH 3。作为催化剂体系,环境友好的水作为溶剂,空气中的氧气作为氧化剂。重要的是,水中的铜催化剂体系是可回收的。该研究应为芳香环上官能团的相互转化提供有用的策略。
